Independent Inspection Effort welds in feedwater lines at the D. C. Cook plant,Due to rec (APC) is in the process of evaluaing similar feedwater lines in the Farley 1 Alabama Power Company plant.
The following is a summary of observations / reviews made and informa-tion obtained by the inspector relative to this problem:
Configuration of Feedwater Lines a.
The steam generator feedwater nozzle is 16 - inches in diameter.
first piping component in the line is a The welded to the nozzle and a 14-inch, 45 degree ell.16-inch x 14-inch reducer The other end of 45-degree angle.the ell is welded to a straight section of pipe which runs d The welds are identified as follows:
Generator "A": Reducer to Nozzle - FW 11, ISO EG-186 Reducer to Ell - FW 6283, ISO, EG-186 Generator "B" Reducer to Nozzle - FW 6, ISO 187 Reducer to Ell FW 6278, ISO EG-187 Generator "C": Reducer to Nozzle FW-15, ISO EG-187 Reducer to Ell - FW 15, ISO EG-187 b.

Pre-Service Inspection - Review of Procedures (Unit 2)
The inspector reviewed the pre-service inspection (PSI) procedures indicated below to determine whether the procedures were consistent with regulatory requirements and licensee committments. The applicable code for the PSI is the ASME Boiler and Pressure Vessel Code,Section XI,1974 Edition, with addenda through the summer of 1975, as required by paragraph 5.2.8 of the FSAR.
a.
ISI-205, revision 2, amendment 3, " Manual Ultrasonic Examination of Full Penetration Circumferential and Longitudinal Butt Welds" This procedure was reviewed in the areas of:
(1) Procedure approval, requirements for qualification of NDE personnel, procedure scope and compilation of required records.
(2) Procedure technical content relative to:
type of apparatus, extent of coverage including beam angle and scanning techniques, calibration requirements, search units, DAC cu rves, reference level for monitoring discontinuities, method of demonstrating penetration, levels for evaluation and recording indications, and acceptance standards.

Pre-Service Inspection - Observation of Work and Work Activities (Unit 2)
The inspector observed the PSI activities described below to determine whether these activities were being performed in accordance with regulatory requirements and licensee procedures.
See paragraph 6.
above for the applicable code.
Personnel qualification records for one level I, four level II and one a.
level III examiners were reviewed.
b.
In process ultrasonic (LTI') inspection, including demonstration of calibration on applicable calibration block, was observed for Weld 28, ISO APR-2-2313 and weld 22, ISO APR-2-2311. The inspection was compared with applicable procedures in the following areas:
